Highlights
In what was a tumultuous month of October for the stock market, the investor movement index ebbed back 0.13 points to 6.10 reflecting reduced volatility of widely held names relative to the increased volatility of the broader market. TD Ameritrade said its clients conducted profit taking and price-specific buying in an orderly manner during the month. Amazon, Apple and Ford were among the buys in the month with selling seen in Qualcomm, Twitter and Gilead Sciences.

Definition
The Investor Movement Index, (or the IMX), is a proprietary, behavior-based index created by TD Ameritrade designed to provide insight into Main Street sentiment. The IMX measures what investors are actually doing, and how they are actually positioned in the markets. The IMX does this by using data representing the holdings/positions, trading activity and other data from an anonymous sample from six million funded accounts. These data are used to create a snapshot that can be monitored over time, or compared to other market indicators, to suggest the current sentiment of the real portfolios held by retail investors.
